Hoisting construction method for oil-immersed high-voltage transformer

Abstract

The invention relates to a hoisting construction method for an oil-immersed high-voltage transformer. According to the transformer hoisting construction method, a transformer hoisting structure is adopted; the transformer hoisting structure comprises a bearing device, a mounting strip, a fixing element, a locking spring, a traction steel wire, an electric pole stand column and a locking circular ring. The supporting device comprises a left supporting plate, a right supporting plate, an embracing mechanism, an overturning pin shaft, a fixing plate and a locking bolt, the embracing mechanism comprises an embracing pin shaft, an embracing hoop and an embracing bolt, and the transformer hoisting construction method adopting the transformer hoisting structure comprises the following steps: S1,supporting and positioning; S2, transformer fixation; S3, top end traction; S4, supporting and lifting. The method can solve the problems that an existing transformer mounting structure is poor in mounting stability, safety and practicability and large in improvement space when an oil-immersed high-voltage transformer is erected and mounted.

Description

technical field [0001] The invention relates to the technical field of transformer installation, in particular to an oil-immersed high-voltage transformer hoisting construction method. Background technique [0002] A transformer is a static electrical device used to convert AC voltage and current to transmit AC power. It is based on the principle of electromagnetic induction to achieve electrical energy transfer. Transformers can be divided into power transformers, test transformers, instrument transformers and special-purpose transformers in terms of their uses: power transformers are necessary equipment for power transmission and distribution, and power distribution for power users; test transformers perform withstand voltage and boost tests on electrical equipment equipment; instrument transformers are used for electrical measurement and relay protection of power distribution systems; transformers for special purposes include electric furnace transformers for smelting, e...

AI Technical Summary

Problems solved by technology

Oil-immersed transformers are commonly used as high-voltage transformers. Due to their high-voltage properties, the safety distance during installation is long, and they often need to be erected at a higher place through poles. When the transformer needs to be erected at a higher place, the transformer is easily received. The interference of external conditions such as wind and other factors makes the power transformer unable to operate safely and stably, and in some extreme weather conditions or when a traffic accident hits the installation pole, the transformer may shake or even fall, threatening public safety; and oil Immersed transformers are flammable. When encountering flames or severe kinetic energy collisions, they may burn or explode, and have a high risk factor. Therefore, the installation stability, safety and practicality of oil-immersed high-voltage transformers need to be obtained when erecting and installing them. High security, the existing oil-immersed transformer installation structure still has a large room for improvement
